The SKF single row tapered roller bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide a true rolling action and therefore low frictional moments during operation. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e the larger the value of e, the larger the contact angle.

Low friction

Enhanced operational reliability

Rigid bearing application

A single row tapered roller bearing is typically adjusted against a second tapered roller bearing. By applying a preload, a rigid bearing application can be achieved.

Running-in period with reduced temperature peaks

Separable and interchangeable

The inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup). Furthermore, the separable components (fig. 6) are interchangeable. This facilitates mounting, dismounting and also maintenance inspection routines.
